针对你遇到的“bpf program load failed: permission denied”问题,以下是一些可能的解决步骤和考虑因素: 确认用户具有加载BPF程序的必要权限: BPF程序通常需要特定的权限来访问内核资源。如果你不是以root用户身份运行程序,可能会遇到权限问题。 尝试以root用户身份运行你的BPF加载程序,例如使用sudo命令: bash sudo ....
The older bpf_program__get_expected_attach_type() didn't declare its argument as const, so the compiler complains about the compatibility wrapper dropping the const qualifier. Add an explicit cast to silence the warning. Signed-off-by: Toke Høiland-Jørgensen <toke@redhat.com>Loading...
I'm on Ubuntu 5.15.0-100-generic built using the instructions for Ubuntu I run: /sbin/offcputime-bpfcc 3 warnings generated. cannot attach kprobe, probe entry may not exist Traceback (most recent call last): File "/sbin/offcputime-bpfcc"...
load_maps bpf_create_map_node fd= bpf_load_program(prog_type, prog, insns_cnt, license, kern_version, bpf_log_buf, BPF_LOG_BUF_SIZE);
libbpf and source get out of sync. The program is only loaded once, so if multiple rules are created only one BPF program is loaded in kernel. The new BPF program only needs a single action. No need for action and re-classification step. ...

1. socket-related program types - SOCKET_FILTER, SK_SKB, SOCK_OPS First, let's consider the socket-related program types which allow us to filter, redirect socket data and monitor socket events. The filtering use case relates to the origins of BPF. When observing the network we want to ...
